Patch for libpng unresolved methods on x86_64 with MMX

[Frederic Simon]

I tried to build b21 on my Ubuntu 7.04 and got:
/work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/png.o:

I found this thread talking about it:
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2007-August/000192.html

So, I tried to modified the makefile to use the system png. It's very
roughly removing the integrated libpng and linking with png12.
Here is the patch:

Hope it helps.
